Laboratory Performance in the Palm of Your Hand
The YSA-P400 series redefines the capabilities of handheld spectrum analysis. Engineered to bridge the gap between field portability and benchtop precision, it delivers ultra-wide frequency coverage from 9 kHz up to 40 GHz with a remarkable Displayed Average Noise Level (DANL) of -161 dBm/Hz and phase noise performance of -107.5 dBc/Hz at 1 GHz (10 kHz offset).
Unlike traditional handhelds, the YSA-P400 features a fully integrated Real-Time Spectrum Analyzer (RTSA) architecture with 100 MHz bandwidth, ensuring 100% probability of intercept for transient signals as short as 15 µs. This makes it an indispensable tool for modern 5G installation, radar pulse analysis, and secure communications monitoring.
Why Handheld?
Traditional benchtop spectrum analyzers deliver excellent performance but are often heavy and bulky, limiting their field deployment capabilities. The YSA-P400 changes the equation:
- Only 1.5 kg — carry it to any site, any rooftop, any mast
- 3 hours of battery life — no mains power required
- External power bank supported — extend operation indefinitely in the field
- 10.1-inch IPS multi-touch display — intuitive gesture control, no external monitor needed
- 40 GHz coverage — matches or exceeds many benchtop units
- -161 dBm/Hz DANL — true laboratory-grade sensitivity in a portable form factor
